Hi phani sri,
I think your assertion is wrong. It looks like the flags fixed your initial issue. The initial error was raised by the compilation step. Now you run into the next issue raised by the linking step (which was never reached in your previous attempts). Please provide more details about the new error messages so that we have a chance to understand your new issue.
Best

Hi Hui, this also did not work. It is ending up with the error: collect2: error: ld returned 1 exit status. On Fri, 17 Oct 2025 at 21: 11, Zhou, Hui <zhouh@ anl. gov> wrote: Hi phani sri, Try set `FFLAGS=-fallow-argument-mismatch` and `FCFLAGS=-fallow-argument-mismatch`

Hi phani sri,
Try set `FFLAGS=-fallow-argument-mismatch` and `FCFLAGS=-fallow-argument-mismatch` and let us know if that helps.
Hui

Hi Gregor, I have checked this, the code is using mpi. h not mpif. h. Dr. D. P. S. L. Kameswari On Fri, 17 Oct 2025, 5: 56 pm Gregor Corbin via discuss, <discuss@ mpich. org> wrote: Hi, let me guess: this code uses `include mpif. h` and is compiled

Hi,
let me guess: this code uses `include mpif.h` and is compiled with gfortran. If so, try to add `-fallow-argument-mismatch' to your compiler flags.
Explanation: With the include file, there are no explicit interfaces and the compiler generates an implicit interface from the call to `MPI_IRECV`. Having two calls with different argument types is an error since some gcc version (10 IIRC).
Cheers,
Gregor Corbin
